Black Vertical Lines on 2019 Macbook Pro

Hi,

The 13 in Macbook Pro is barely 1 month old and it currently developed a thin black vertical line to the right of the screen. It comes and go and if I gently press the bottom of the screen it flickers or changes location, indicating possibly a hardware issue.

The thing is, in Safe Mode I do not see the line at all.

Any suggestions for a quick fix before taking it to the service center?

I already had the hardware test and it came back negative.

Cheers.

Yes, the reason for that is because the screenshot bypasses the display and comes straight from the GPU, while the photo is capturing the display. So it's a glitch in the display. I'd still see if Apple Diagnostics turns anything up. I'd also try cleaning the display with a soft cloth to be sure nothing is on the surface.

You're welcome. Since this is a new Mac, you get 90 days of free telephone support. (800)MYAPPLE in US. I'd call and open up a ticket on that. Also if you're near an Apple Store make a Genius Bar appointment and bring it in for them to evaluate.

Try running Apple Diagnostics and see if it turns up anything.

Apple Diagnostics is not the sensitive test for hardware. Just because it reports OK doesn't mean a problem doesn't exist but if it reports a problem you can be sure there is one.

Another thing I'd like to see is a screenshot of the issue. You can use the image insertion icon at the bottom of your reply window to post it.

Not sure what you mean about resetting time? An NVRAM reset wouldn't reset time unless it had been incorrect.

Try an NVRAM reset:

Hi,

I have attached a screenshot (you cannot see the line) and also a pic taken with my phone. You can see the dark line between the US flag and the search loupe.
